Identification of longitudinal section (L.S) of the human heart - Bio-Zoology Laboratory Practical Experiment
Identification of longitudinal section (L.S) of the human heart.
Aim:
To observe and draw a labelled sketch of L.S of human heart and write the structure.
Materials Required:
Model showing the L.S of human heart
Observation:
The given model is identified as L.S. of human heart
- The human heart has four chambers. It is made up of two auricles and two ventricles
- The chambers are separated by interauricular and interventricular septum. It prevents the mixing of oxygenated and deoxygenated blood.
- Tricuspid valve - It is located between the right auricle and the right ventricle
- Bicuspid valve - It is located between the left auricle and the left ventricle
- The heart is covered by a protective double walled membrane called pericardium
- The heart pumps blood to all parts of the body.
