The blood-brain barrier consists of tight junctions between which of the following? a. Neurons b. Astrocytes c. Endothelial cells d. Epithelial cells
c. Endothelial cells What are the major components of the cardiovascular system?
The major components of the cardiovascular system are the heart, blood, and blood vessels. Which of the following is not found in blood plasma? a. Water b. Electrolytes c. Red blood cells d. Proteins
c. Red blood cells Which of the following has higher levels in capillary blood than in venous blood? a. Oxygen b. Carbon dioxide c. Nutrients d. Waste products
a. Oxygen Which action should be taken to slow the flow of blood from the wound of someone who is bleeding?
To slow the flow of blood from a wound, apply direct pressure to the wound site. Which is the most abundant type of plasma protein?
Albumin is the most abundant type of plasma protein. The circulatory system transports white blood cells to fight infections for which system?
The circulatory system transports white blood cells to fight infections for the immune system. Which of the following would lead to anemic hypoxia? a. Low hemoglobin levels b. High blood pressure c. Increased red blood cell count d. High oxygen levels
a. Low hemoglobin levels What are the three main functions of blood in the human body?
The three main functions of blood are transport (of oxygen, nutrients, hormones, and waste), regulation (of body temperature, pH, and fluid volume), and protection (against blood loss and infection). What percentage of an adult's body mass is made up of blood, and how many liters does this typically represent?
Blood makes up about 8% of an adult's body mass, which is typically 4 to 6 liters. Which component of blood is responsible for its red color and what is its primary function?
Erythrocytes (red blood cells) are responsible for blood's red color and primarily function in transporting oxygen and carbon dioxide. What is plasma, and what are its main components?
Plasma is the nonliving, liquid extracellular matrix of blood, consisting of about 90% water, electrolytes, and proteins such as albumin and globulins. How does blood contribute to the protection of the body?
Blood protects the body by forming clots to prevent blood loss and by containing immune cells that defend against infection. What is the function of platelets in the blood?
Platelets (thrombocytes) are cell fragments that play a key role in blood clotting to prevent blood loss after injury. Why is blood considered a connective tissue?
Blood is considered a connective tissue because it consists of living cells (formed elements) suspended in a nonliving extracellular matrix (plasma). How does blood maintain pH balance in the body?
Blood maintains pH balance using buffers that help keep the pH within the narrow range of 7.35 to 7.45. What happens to the color of blood depending on its oxygen content?
Blood is bright red when oxygen-rich and darker red when oxygen-poor. How does blood transport waste products, and where are they eliminated?
Blood transports waste products like carbon dioxide to elimination sites such as the lungs, where they are expelled from the body.
