Tissues
This primary tissue type is responsible for support, including physical and nutrient support
What is connective tissue?
These structures, especially found in the limbs, are contained within veins to prevent the backflow of blood
What are valves?
Mechanical digestion and processing first occur in this location
What is the mouth?
These are the male gonads, responsible for producing sperm and androgens
What are the testes?
This contains only the thick filament of the sarcomere
What is the H band?
This characteristic describes epithelial tissue's composition primarily of cells, with very little space between them
What is high cellularity?
This is the primary role of capillaries, involving the exchange of oxygen, carbon dioxide, nutrients, and waste products between blood and surrounding tissues
What is the facilitation of gas exchange?
This hormone is released in the stomach, prompting the release of hydrochloric acid to kill bacteria and maintain an acidic environment
What is Gastrin?
This hormone signals the release of the egg (ovulation) and increases progesterone to maintain the uterine lining and prepare the body for pregnancy
What is leutanizing hormone (LH)?
the cell responsible for touch reception in the skin
What are Merkel Cells?
This specific type of cartilage reduces friction between bony surfaces
What is hyaline cartilage?
This middle layer of blood vessel walls, composed of smooth muscle and elastic tissue, is thicker in arteries than in veins to regulate and withstand high pressure
What is the tunica media?
This segment of the small intestine is the site where Vitamin B12 is absorbed
What is the ileum?
This accessory gland secretes a milky, alkaline fluid that provides nourishment and protection for sperm
What is the prostate gland?
A blood condition occurs when the body lacks enough healthy red blood cells due to low hemoglobin or iron
What is anemia?
What are adipose, areolar, and reticular?
This fetal circulation shunt connects the pulmonary artery to the aorta, directing blood away from the non-functional fetal lungs
What is the ductus arteriosus?
This structural feature, absent in the large intestine, is found in the small intestine to increase the surface area for absorption
What are Villi?
This phase of the ovarian cycle occurs on days 15-28, during which the corpus luteum secretes progesterone and estrogen to stabilize the uterine lining
What is the luteal phase?
These are the three main plasma proteins
What are fibrinogen (clotting), albumin (water retention), and globulins (transport)?
In nervous tissue, these structures receive the impulse, while the structure that is often myelinated sends the message
What are dendrites and the axon?
This main vessel of the hepatic portal system carries nutrient-rich blood from digestive organs like the intestines and stomach directly to the liver
What is the hepatic portal vein?
These cells secrete pepsinogen, which is activated by hydrochloric acid (HCl) to become pepsin, which breaks down proteins in the stomach
What are chief cells?
Unlike oogenesis, which begins in the fetus, spermatogenesis (sperm development) does not begin until this phase of life
What is puberty?
The myelin sheath of the CNS and the myelin sheath of the PNS
What is oligodendrocytes and Schwann cells?
