Question

name: lab: homeostasis - physiology

1. what are tissue(s), and organ(s) that are a part of the respiratory system?
2. what are the primary functions of the respiratory system?
3. what are the cell(s), tissues, and organ(s) that are a part of the circulatory system?
4. what are the primary functions of the circulatory system?
5. explain the process of gas exchange for oxygen and co2 between alveoli and capillary.
6. what are the cell(s), tissues, and organ(s) that are a part of the digestive system?
7. what are the cell(s), tissues, and organ(s) that are a part of the endocrine system?

Explanation:

1. Tissues in the respiratory system include epithelial tissue (e.g., ciliated columnar epithelium) lining the air - ways. Organs are the nose, pharynx, larynx, trachea, bronchi, and lungs.
2. The primary functions of the respiratory system are gas exchange (taking in oxygen and expelling carbon dioxide), acid - base balance regulation, and vocalization.
3. Cells in the circulatory system include red blood cells, white blood cells, and platelets. Tissues are the endothelial tissue lining blood vessels and cardiac muscle tissue in the heart. Organs are the heart, blood vessels (arteries, veins, capillaries).
4. The primary functions of the circulatory system are transporting oxygen, nutrients, hormones, and waste products; maintaining body temperature; and protecting against disease.
5. In the alveoli - capillary gas exchange, oxygen diffuses from the alveoli (high oxygen concentration) into the capillaries (low oxygen concentration) due to a concentration gradient. Carbon dioxide diffuses from the capillaries (high CO2 concentration) into the alveoli (low CO2 concentration).
6. Cells in the digestive system include enterocytes and goblet cells. Tissues are epithelial tissue lining the digestive tract and smooth muscle tissue for peristalsis. Organs are the mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder, and pancreas.
7. Cells in the endocrine system include endocrine cells (e.g., beta cells in the pancreas). Tissues are endocrine tissues. Organs are the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries (in females), and testes (in males).

Answer:

1. Epithelial tissue (e.g., ciliated columnar epithelium), nose, pharynx, larynx, trachea, bronchi, lungs
2. Gas exchange, acid - base balance regulation, vocalization
3. Red blood cells, white blood cells, platelets; endothelial tissue, cardiac muscle tissue; heart, blood vessels (arteries, veins, capillaries)
4. Transporting oxygen, nutrients, hormones, waste products; maintaining body temperature; protecting against disease
5. Oxygen diffuses from alveoli to capillaries, carbon dioxide diffuses from capillaries to alveoli due to concentration gradients
6. Enterocytes, goblet cells; epithelial tissue, smooth muscle tissue; mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder, pancreas
7. Endocrine cells (e.g., beta cells in the pancreas); endocrine tissues; pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries (in females), testes (in males)
