Qs Two Contraction Cycles - n Ans✔ systole (contraction of heart muscles) and diastole (relaxation of heart muscles) Qs Arteries - n Ans✔ thick-walled blood vessels that carry blood away from the heart to deliver oxygenated blood to body tissues Qs Atria - n Ans✔ the two upper chambers of the heart Qs Lymph - n Ans✔ a watery, plasma-like fluid that contains white blood cells. It flows through tissues and vessels, eventually entering the large veins that return to the heart Qs
Plasma - n Ans✔ contains nutrients, hormones, antibodies, and other immune proteins Qs Platelets (thrombocytes) - n Ans✔ form blood clots to stop or control bleeding Qs Red Blood Cells (erythrocytes) - n Ans✔ contain hemoglobin and transport oxygen and carbon dioxide Qs Valves - n Ans✔ flaps of leaflets that prevent blood from flowing backward. The four main heart valves are the tricuspid (between right atrium and right ventricle), pulmonary (between right ventricle and pulmonary artery), mitral (between left atrium and left ventricle), aortic (between left ventricle and aorta) Qs Veins - n Ans✔ blood vessels that carry deoxygenated blood from the body back to the heart Qs
water and vitamin k, and the waste products are moved into the rectum for storage before evacuation. Qs 3 Main Secretions of the Stomach - n Ans✔ pepsinogen (chief cells), mucus (goblet cells), and hydrochloric acid (parietal cells) Qs Duodenum - n Ans✔ the first part of the small intestine, uses alkaline bile (a fluid produced in the liver and stored in the gallbladder) to help neutralize chyme, an acidic substance containing gastric juices and partially digested food Qs Enzymes - n Ans✔ proteins that act as catalyst to expedite the chemical reactions that break down food into usable substances Qs Hormones - n Ans✔ have key roles in many aspects of digestion including regulating the sensations of hunger and satiety, stimulating secretions and glucose uptake, modulating digestive action and movement of food through the small intestine, and including glycogen breakdown Qs
Mouth - n Ans✔ Enzymes: salivary amylase, salivary lipase. Major hormones: none Qs Stomach - n Ans✔ Enzymes: gastric lipase, pepsin (ogen). Major hormones: gastrin, ghrelin Qs Pancreas - n Ans✔ Enzymes: pancreatic juice, protease. Major hormones: secretin, somatostatin, insulin, glucagon Qs Small intestine - n Ans✔ brush border enzymes. Major hormones: cholecystokinin Qs Nervous System (main functions) - n Ans✔ controls involuntary and voluntary movement, sends motor signals, takes in and processes information from the body and the environment Qs
Neuron - n Ans✔ nerve cell. Includes the cell body, dendrite, axon (with terminal), and myelin sheath Qs Afferent Neuron - n Ans✔ transmit sensory information to the CNS Qs Efferent Neuron - n Ans✔ send messages to the muscles Qs Neurotransmitters - n Ans✔ chemical messengers secreted from the axon terminals of neurons into the synapses (small gaps at the ends of neurons). They carry signals from neurons to other neurons or to muscle cells. Qs Muscular System - n Ans✔ along with the nervous system, controls involuntary and voluntary movement Qs
3 Types of Muscle Tissue - n Ans✔ skeletal (striated, strong, associated with voluntary muscle movement), smooth (non- striated, associated with autonomic nervous systems, "involuntary movement"), and cardiac (heart muscle, striated, has internal pacemaker) Qs Muscles - n Ans✔ soft tissues, or myofibrils, made up of sarcomere units, each containing long strands of actin (thin protein filaments) and myosin (thick protein filaments). Muscle fibers are connected to nerve fibers and respond to nerve impulses to produce force and motion. The actin and myosin filaments slide past each other to contract or relax the muscle. Most skeletal muscles attach to bones by tendons. Qs Adenosine Triphosphate (ATP) - n Ans✔ a compound that provides energy to cells. It is needed for muscle movement. It is generated from food by mitochondria Qs Striations - n Ans✔ light and dark bands on skeletal and cardiac muscle, caused by the sliding of myosin and actin filaments Qs Tendons - n
Ans✔ ovaries, Fallopian tubes, uterus, cervix, vagina, labia majora and minora, clitoris Qs Estrogen - n Ans✔ is made in the ovaries and causes the egg to mature and the uterine endometrium to thicken Qs Fertilization - n Ans✔ fusion of the egg and sperm which occurs in the Fallopian tube. A fertilized egg (zygote) divides and becomes a blastocyst. Qs Implantation - n Ans✔ attachment in the uterus of a blastocyst, which develop into an embryo and then fetus Qs Placenta - n Ans✔ temporary organ that forms during pregnancy to nourish the growing embryo/fetus and remove waste products. It gives rise to the umbilical cord Qs Integumentary System (main functions) - n
Ans✔ protects the body from pathogens and the environment; regulates temperature Qs Integumentary system (main structures) - n Ans✔ skin (the body's largest organ); hair; nails; and sebaceous (sebum), sudoriferous (sweat), and ceruminous (earwax) glands Qs Thermoregulation - n Ans✔ when the body is too warm, sweat is produced and released. When the body is too cold, blood vessels constrict, reducing the amount of blood brought to the skin's surface Qs What does the skin produce when exposed to ultraviolet light? - n Ans✔ vitamin D Qs 3 Main layers of the skin - n Ans✔ epidermis (contains melanocytes, which affect skin pigment), dermis (contains hair follicles, nerve endings, blood vessels, glands), and hypodermic (or subcutaneous layer) Qs What is the integumentary system's responsibility? - n
at the hypothalamus in the brain. The nervous system uses electrical impulses to send signals to the hypothalamus, which secretes releasing or inhibiting hormones to the pituitary Qs The pituitary - n Ans✔ acts as a "master gland" by releasing hormones to other parts of the body Qs Homeostasis - n Ans✔ the state of maintaining a steady internal environment. A self-regulating process, it works mainly through negative feedback loops and hormone regulation in response to changes Qs Urinary system (main function) - n Ans✔ excretion Qs Urinary system (main organs) - n Ans✔ kidneys, ureters, urinary bladder, and urethra Qs Kidneys - n Ans✔
filter blood to remove waste (particularly nitrogenous waste from protein digestion), manufacture urine, balance body fluids, produce renin to help regulate blood pressure, release the hormone erythropoietin to stimulate red blood cell formation, and produce active form of vitamin D Qs Nephron - n Ans✔ functional unit of the kidney. Blood is filtered in the glomerulus, and filtrate is carried away through the tubule Qs Ureters - n Ans✔ small tubes that carry urine to the urinary bladder, where it is held until it is released through the urethra. Males have. longer urethra, which passes through the penis and carries both urine and semen Qs Immune system (main function) - n Ans✔ protects the body from pathogens. Two major components: innate and adaptive Qs Innate immune system - n Ans✔ a series of nonspecific barriers, consists of both external physical barriers (skin, hair mucus, earwax) and internal barriers in the form of cellular and chemical responses (including the inflammatory response, phagocytes, antimicrobial peptides, interferons,
