Role of Liver - ANSWER: *Enzymes from liver deaminate amino acids
*convert ammonia to urea
*metabolize consumed toxins
store glucose to glycogen
Chyme - ANSWER: Stomach secretion mixture
includes mucus (lines the stomach), hydrochloric acid, and pepsinogen
Cytotoxic T cell - ANSWER: *Recruited by helper T cell via cytokinesis
*kill any cell containing pathogens antigen signature
Role of Duodenum - ANSWER: *First portion of the small intestine
*most chemical digestion here but no real absorption
*Pancreatic secretions collect here for neutralizing HCl
*Gallbladder Bile is alkaline to help neutralize acid
*brush border enzymes produced here
Role of Jejunum - ANSWER: absorption of nutrients mostly here
bronchopulmonary segments - ANSWER: Each lung lobe has its own bronchus and own
artery
olecranial - ANSWER: Back of elbow
Pepsinogen - ANSWER: *enzyme that breaks down peptides in the stomach
*found in chyme
*is converted to pepsin
,Macrophage - ANSWER: *AKA Antigen-presenting cell
*digests pathogens and presents antigen to helper T Cell
Role of Large Intestine - ANSWER: *absorbs remaining water; Salts
*Vitamin K absorbed here
*digested material exposed to bacterial fermination
Renin - ANSWER: *hormone that regulates retention of water and salts; stimulates release
of aldosterone that helps retain water and salts
*regulates BP in controlling water and salt retention
Male Gamete production - ANSWER: *LH released in testes to produce more testosterone
*sperm production when testosterone and FSH released in the testes
High Blood sugar - ANSWER: increase glucose signals pancreatic beta-cells to release
insulin, promoting cell uptake to decrease BG
Lacteals - ANSWER: lymphatic vessels of small intestine that absorb digested lipids
Ileum characteristics - ANSWER: Absorbs what jejunum doesnt absorb
absorb polar hydrophilic digested nutrients into blood
*Absorb Lipids (into chylomicrons transporters) and Vitamin B12
Histamines - ANSWER: *part of innate (natural) immunity
*causes local swelling and recruits WBCs
Perineal - ANSWER: b/w anus and genitals
Erythropoietin - ANSWER: *produced in the renal cortex
*hormone for RBC production
, Female Zygote Implantation - ANSWER: *Corpus luteum: empty ovary follicle stimulate
release of progesterone
*progesterone promotes zygote implantation on the uterine endometrium
innate immunity - ANSWER: *non-specific immune response
*first line of defenses are the skin, mucus secretions
*our microbiota help fight certain pathogens
Sural - ANSWER: Calf
Female Gamete production - ANSWER: *FSH released in ovaries to produce more
estrogen
*Estrogen cause ova to mature in ovaries' follicle and causes uterine endometrium to thicken
*LH surge causes ovum to be release into fallopian tube to be fertilized
Interfereons - ANSWER: protein that interferes with viral replication in host cells
Natural Killer Cells - ANSWER: Kill host cells w/ intracellular pathogens (Ex: virus)
Adaptive immunity - ANSWER: *Specific response to specific pathogen
*Immune response when innate immunity fails
Amylase - ANSWER: *Enzyme in saliva
*breaks down starch (carbohydrates)
buccal - ANSWER: cheek
Granulocytes - ANSWER: *basophils, eosinophils, neutrophils
*derived from myeloblast
