Main functions of muscles in the human body

Back

- Producing movement - Stabilising body position - Movement of substances - Regulating organ movement - Producing heat

Front

Properties of muscle tissue: Excitability

Back

Muscle tissue can respond to a stimulus, generating an electrical signal triggering muscle activity.

Front

Properties of muscle tissue: Contractility

Back

Muscle tissue can actively contract (shorten), producing force to move bones and perform other functions.

Front

Properties of muscle tissue: Elasticity

Back

Muscle tissue can stretch but is able to return/contract to its original shape.

Front

Properties of muscle tissue: Extensibility

Back

The ability of muscle tissue to be stretched or extended beyond relaxed length without being damaged.

Front

Role of fascia in muscle functioning

Back

Fascia is connective tissue that surrounds the muscles, providing protection and stability to the muscles.

Front

Protein filaments that slide past each other during muscle contraction

Back

Actin and Myosin

Front

Percentage of blood volume made up of plasma

Back

Plasma makes up about 55% of blood volume and is mostly comprised of water, with the rest being proteins, nutrients, electrolytes, waste products, hormones, and enzymes.

Structure and function of erythrocytes

Back

- Erythrocytes are small, round biconcave discs that don’t have a nucleus and contain large amounts of hemoglobin. - They transport oxygen from lungs to heart and carry carbon dioxide from tissues to the heart.

Front

Types of leukocytes and their functions

Back

1. Monocytes – Becomes macrophages (pathogens that engulf viruses) 2. Neutrophils – Uses phagocytes to engulf bacteria 3. Eosinophils – Uses enzymes to digest parasitic worms 4. Basophils – Releases histamine 5. Lymphocytes –
