Deoxygenated blood from the body returns to the heart through veins. The heart then pumps the deoxygenated blood through pulmonary arteries to the lungs. In the lungs, the deoxygenated blood gets oxygen from air in the lungs, and the carbon dioxide is removed. The oxygenated blood is then returned to the heart through the pulmonary veins before being sent to the body through the main artery, the aorta.

Based on the above passage, identify the two body systems that are not directly involved these functions.

The movement of water, containing no solute, across semi-permeable cellular membranes through proteins called aquaporins is known as **osmosis**.
Answered by GPT-4o mini
A distinguishing feature between smooth endoplasmic reticulum and rough endoplasmic reticulum is that **rough endoplasmic reticulum has ribosomes attached to its surface**.
Answered by GPT-4o mini
The structure lacking a membrane that is present in plant cells and not in animal cells is the **cell wall**.
Answered by GPT-4o mini
The correct answer is **a spinal column**. Invertebrates do not have a spinal column, while vertebrates do.
Answered by GPT-4o mini
The organs in the digestive system involved only in the chemical digestion of food are the **small intestine** and the **stomach**.
Answered by GPT-4o mini
Based on the passage, the two body systems that are not directly involved in these functions are the **digestive and endocrine** systems.
