Study Notes
Heart Function
- The heart serves as a muscular pump for systemic blood circulation.
- It delivers essential nutrients including amino acids, carbohydrates, lipids, vitamins, and minerals throughout the body.
- The heart facilitates the removal of waste products, specifically carbon dioxide (CO2) exhaled from the lungs and urea excreted by the kidneys.
- Hormones, which act as signaling molecules, are also transported by the heart.
- Functional proteins in the blood, such as antibodies, albumin, and lipoproteins, are carried by the heart.
Interdependence with Other Organs
- Heart function is closely interlinked with lung and kidney functions.
- Cardiovascular health should be assessed in conjunction with lung and kidney performance due to their interconnected roles in bodily functions.
Mediastinum – Heart Location
- The heart is situated centrally within the bony thoracic rib cage.
- Humans possess 12 pairs of ribs that connect posteriorly to the vertebrae and anteriorly to the sternum.
- The ribs articulate with the sternum via costal cartilage.
