Endocrine System Quiz

Endocrine System

• The neural control center for all endocrine systems in vertebrates is the hypothalamus.
• The pancreas, although having endocrine functions, is not typically classified as a major endocrine gland in humans.

Kidney Functions

• The kidney secretes the hormone erythropoietin (EPO) as part of its endocrine function.
• The kidney plays a crucial role in the production of red blood cells through the secretion of EPO.

Pituitary Gland and Nervous System

• The pituitary gland links the endocrine system to the nervous system.
• The pituitary gland acts as a bridge between the two systems, facilitating communication and coordination.

Secondary Endocrine Functions

• The kidney, apart from its primary role in filtration and waste removal, has secondary endocrine functions.
• The heart, apart from its primary role in pumping blood, has secondary endocrine functions.

Blood Components

• The main protein in plasma is albumin, which maintains osmotic pressure and transports lipids and hormones.
• Hemoglobin in red blood cells is responsible for transporting oxygen from the lungs to the body's tissues.
• Deoxygenated vertebrate blood is blue-purple in color.
• Plasma constitutes the majority of blood fluid, making up about 55% of total blood volume.

White Blood Cells
