1. the aorta is the only artery that supplies the groin and lower extremities with blood.
2. the knee is a ball - and - socket joint.
3. the phalanges are the bones of the fingers and toes.
4. the right atrium receives blood from the pulmonary veins.
5. there are 10 ribs located in the thorax.
6. exhaled air contains 21% oxygen.
7. the spleen is a solid organ that is commonly injured in abdominal blunt - trauma injuries.

Explanation:

• Multiple - choice questions:
• The endocrine system releases hormones (chemicals) that regulate body activities. The nervous system uses electrical and chemical signals but in a different context. The cardiovascular system circulates blood and the skeletal system provides support and protection.
• The pulmonary artery carries de - oxygenated blood from the heart to the lungs, while the inferior vena cava, superior vena cava, and pulmonary veins carry blood to the heart.
• The liver produces bile which is transported to the intestine via the bile ducts.
• The urinary system is involved in fluid control, pH balancing, and waste filtration, but not hormone regulation. Hormone regulation is mainly done by the endocrine system.
• The pancreas secretes pancreatic juice containing enzymes for digesting fats, starches, and proteins.
• True/False questions:
• The aorta branches into other arteries to supply the groin and lower extremities, so it is not the only one.
• The knee is a hinge joint, not a ball - and - socket joint.
• The phalanges are the bones of the fingers and toes.
• The left atrium receives blood from the pulmonary veins, not the right atrium.
• There are 12 pairs of ribs in the thorax.
• Exhaled air contains about 16% oxygen.
• The spleen is a solid organ and is commonly injured in abdominal blunt - trauma injuries.
