A&P Flashcards
Esophagus -> Intestine, Which muscle helps digest?
Peristalsis
Which Valve is at the Junction of the small and large intestine?
Ileocecal Valve
Bases of Aorta and pulmonary Artery, has each
Semilunar Valve
What is the Pyloric Valve
Junction b/t stomach and small intestine
Produces Calcitonin as well as Iodine-containing hormones Thyroxine and Triiodothyronine.
Thyroid Gland
What does the Iodine-containing hormones do?
It influences growth, development, and overall metabolic rates
What does Calcitonin do
Lowers blood calcium level
What is a Sarcomere
Actin and Myosin, separated by Z Disk, ultimately repeating unit of myofibril.
Cell Surface Receptor
Steroid hormones such as estrogen, testosterone, and progesterone bind to nuclear receptors not cell surfaces.
Insulin will bind to a cell-surface receptor.
Vessel carries blood away from the liver and toward the heart?
Hepatic Vein
A patient is examined for liver disease and has juandice, a yellow coloring of the skin. What may be the cause of the yellow coloring?
Excess bilirubin.
Liver problems can prevent the normal removal of bile pigments via the digestive tract. If bile pigments such as bilirubin get into circulation, they can cause skin discoloration.
Cellular Abundance.
Platelets, leukocytes, erythrocytes
Erythrocytes(RBC)> leukocytes(WBC)> Platelets(tiny cells that forms blood clots)
Which common source are they developed from?
Pluripotent Stem cell
Erythropoietin?
Is a hormone released primarily from the kidneys and will stimulate RBC formation in the bone marrow.
During an injury, histamine will..
Cause vasodilatation, and will allow WBC to squeeze out of the capillaries.
Myeloma Cell?
myeloma cell is a cancer cell with the ability for indefinite growth.
Lymphocyte + myeloma cell?
Hybridoma cell, produces desired antibody.
In insects, molting and metamorphosis are regulated by ?
Ecdysone
Adrenal gland produces which hormones?
Epinephrine, aldosterone, and cortisol.
One trimester is..important
B/c is the main period in which organs are formed and is most sensitive to drugs and radiation
The lymphatic system does three major things.
- Returns excess interstitial fluid to the blood.2. absorbs fats and fat-soluble vitamins from the digestive system and transports them to the venous circulation3. defense against micro-organism. Lymphatic organs such as the spleen contains lymphocytes.
The role of microvilli and villi associated with the small intestine
Increasing the absorption surface
Sarcoma occurs only in connective tissue
“Fleshy growth” cancerous growth in connective tissue. Normal connective tissue include, fat, blood vessels, nerves, bones, muscles, deep skin tissues, and cartilage
