Veterinary Physiology Paper I Quiz

Blood Composition and Function

• Copper is present in the hemoglobin of octopuses, which gives it a blue-green color.
• Iron gives the red color to the blood in humans and some other animals.

Octopus Physiology

• An octopus has three hearts.

Unusual Blood Colors

• The sea cucumber has green-colored blood due to the presence of a green pigment called bilin.
• Some invertebrates, such as starfish and sea urchins, have colorless blood.

Blood Components

• Plasma is the liquid portion of the blood that makes up about 55% of its total volume, and its main function is to transport proteins, nutrients, hormones, and gases throughout the body.

Serum vs. Plasma

• Serum is the liquid portion of the blood that remains after blood has clotted, whereas plasma is the liquid portion of the blood before clotting.
• The main difference between plasma and serum is that plasma contains clotting factors, which are removed during the clotting process to form serum.

Non-Protein Nitrogen (NPN) Compounds

• NPN compounds, such as urea, uric acid, and creatinine, are waste products in the blood that are transported to the excretory organs for removal.

Erythrocyte Function

• Erythrocytes, also known as red blood cells, play a crucial role in mammals by carrying oxygen from the lungs to the body's tissues and carbon dioxide from the tissues to the lungs.

Homeostasis

• Maintaining homeostasis in extra-cellular fluid is essential to ensure proper cellular function, as it helps regulate pH, temperature, and the balance of essential ions and nutrients.
