Explanation:
Hopefully this is right:
Comes in through superior and inferior vena cava, then enters right atrium, then tricuspid valve and into the right ventricle. Then the deoxygenated blood gets pumped through the pulmonary artery to the lungs. Oxygenated blood comes back through pulmonary vein and into left atrium.

A patient is helped into a dorsal recumbent position so they may be examined by a medical assistant. The patient is positioned in this posture by lying face up, with the feet flat on the table and the legs bent.
The dorsal recumbent position is used for preparation for an exam like vaginal examinations, using obstetric forceps, and other operations. The patient is positioned on their back with their lower limbs flexed and turned outward. It is one of the frequently utilized dorsal or supine postures in clinical practices. Additionally, the terms "supine posture" and "dorsal recumbent position" are sometimes interchanged. To be more specific though, there is little distinction between the two locations.

- The muscles represent one of the four types of tissues (the remining include connective tissue, nerve tissue and epithelial tissue) found in the human body.
- A muscle is a group of cells that contract together as a unit in order to produce a force.
- Muscles can be divided into skeletal (voluntary) muscles, smooth (involuntary) muscles, and cardiac (involuntary) muscles.
In conclusion, the human body contains approximately 640 muscles.
