Study Notes
Cell Cycle
- The primary function of the cell cycle is to produce new cells for growth and repair.
- The cell spends most of its time in interphase, which is the phase between cell divisions.
Respiration
- The primary gas exchanged during breathing in humans is oxygen.
Nervous Tissue
- Nervous tissue is responsible for transmitting electrical signals throughout the body, enabling communication and coordination.
Mitosis
- The outcome of mitotic cell division is the production of two identical daughter cells, each with the same number of chromosomes as the parent cell.
Cell Cycle & Division
- The cell cycle is a sequence of events that take place in a cell leading to its duplication.
- The majority of a cell's life is spent in interphase, where it grows and carries out its normal functions.
- A cell's preparation for division takes place during interphase.
- Mitosis is the process that results in two daughter cells that are genetically identical to the parent cell.
Respiration & Gas Exchange
- Breathing involves the exchange of gases, primarily oxygen (O2) and carbon dioxide (CO2).
- Oxygen is transported in the blood bound to hemoglobin, a protein found in red blood cells.
- The process of cellular respiration utilizes oxygen and releases carbon dioxide which initiates gas exchange.
Tissue Types
- Nervous tissue is responsible for transmitting electrical signals throughout the body.
- Connective tissue provides support and protection to different organs.
