The flow of oxygen is simply summarized as entering the body through the lungs and being absorbed into the blood. From there, the oxygenated blood is carried to the heart and then pumped all over the body. From there, the oxygen is absorbed by cells that need it for respiration.
Carbon dioxide is generated via respiration of glucose in muscle and body cells. It then passes into the blood and is carried out to the lungs, where it diffuses out and is breathed out.
Blood follows a double circulation pattern, where deoxygenated is pumped to the lungs from the heart then goes back to the heart to be pumped into the rest of the body.
Answer:
Option C, Intrapleural pressure is less than intrapulmonary pressure
Explanation:
During inspiration, the air enters the lungs due to lower pressure in the intrapulmonary or intra-alveolar than the atmospheric pressure. During quite respiration, the intrapulmonary pressure reduces to a pressure that is 3 mm Hg lower than that of atmospheric pressure. During quiet expiration, the intrapulmonary pressure rises up to a pressure that is 3 mm Hg higher than that of atmospheric pressure. This leads to lack of air in the intrapleural space thereby producing intrapleural pressure which is lesser than that of intrapulmonary pressure.
This difference in pressure (i.e higher pressure with in the lungs than the atmosphere) causes lungs to remain attached to the chest wall and hence looks inflated.
Hence, option C is correct
Answer:
75% would have the dominant traits for coat length, 25% would have recessive trait for coat length.
Explanation:
After completing a punnet square, we could find that our genotypes are 25% LL, 50% Ll, and 25% ll.
If these genotypes were to be physically expressed, LL and Ll would both be expressed as showing the dominant trait.
This means that 75% would have the dominant traits for coat length and 25% would have recessive trait for coat length.

Answer:
Optic Chiasm
Explanation:
Optic nerves travel through the optic chiasm to ensure that visual signals go to each hemisphere of the brain.
