Anatomy And Physiology-blood

1. What are some characteristics of blood?

1) pH between 6.5 and 7.0

3) composes about 15% of body weight (approximately 1 gallon)

1) 7.35 and 7.452) 38 degrees C or 100.4 degrees F3) 8%4) 6 quarts5) 5X

2) 32 degrees C or 89.6 degrees F

Blood has specific characteristics that are crucial for its proper functioning in the human body. The pH, temperature, composition of body weight, and viscosity are all important factors to consider.

2. What are the main functions of blood?

1) Transports2) interstitial fluid3) Heat

Filters lymphatic fluid

Produces insulin

Carries DNA

Blood primarily functions to transport nutrients, oxygen, wastes, hormones, maintain the stability of interstitial fluid, and distribute heat throughout the body.

1) Red2) Gases3) surface area4) hemoglobin

The question is about the characteristics of red blood cells (erythrocytes) and how their shape aids in the transport of gases. The correct answers highlight the important features of red blood cells and their function in oxygen transport.

4. What happens to RBCs as they age?

2) Neutrophils destroy damaged RBCs in the liver and spleen

1) They become stronger and healthier

3) Iron molecules are released and recycled

1) fragile and damaged2) Macrophages 3) Hemoglobin molecules

As red blood cells (RBCs) age, they become fragile and damaged, leading to their removal by macrophages in the liver and spleen, where hemoglobin molecules are released and recycled.
