Red Blood Cells

  • Transport of oxygen and carbon dioxide throughout the body.

  • contains hemoglobin in their cytoplasm

  • biconcave disc shape

  • fairly flexible

  • has no nucleus

  • eukaryotic and are produced in bone marrow. They are vital for maintaining proper blood function and overall oxygen delivery to tissues. They facilitate gas exchange due to their unique structure and abundant hemoglobin content.

Muscle Cells

  • shorten or lengthen its length to produce movement

  • made up of many myofibrils

  • well supplied with blood vessels and nerves, enabling efficient contraction and energy supply.

Nerve Cells

  • transmission or conduction of impulses

  • structure: elongated so that nerves can run to and from different parts of the body to the CNS

  • cell has axons and dendrites

  • axon is covered with a fatty sheath

Sperm Cell

  • male reproductive cell that fertilizes the ovum, characterized by a flagellum for swimming and a compact head containing genetic material.

  • head contains genetic material from the father

  • acrosome in the head contains a digestive enzyme

  • mid-piece is packed with mitochondria (produce ATP (adenosine triphosphate), fueling the sperm’s movement as it swims toward the egg for fertilization.)

  • tail enables the sperm to swim towards the egg for fertilization

Egg Cell

  • female reproductive cell that is typically larger than the sperm and contains nutrients for the developing embryo. The cytoplasm is rich in organelles and genetic material, waiting to be fertilized by the sperm.

  • has a nucleus

  • contains a lot of cytoplasm

  • cell membrane changes after fertilization to prevent mutliple sperm from entering

<p>Epithelial cell</p>

Epithelial cell

  • sensory receptors as they line major cavities in the body

  • responsible for making new cells

  • sheets of tissue bound together → epithelia

  • tissue formed lacks blood

  • varying shapes that cover body surfaces and line cavities. They serve protective, absorptive, and secretory functions.
