1st phase- Bolus(chewed, moistened and lubricated by saliva), is moved to the pharynx from the upper surface of the tongue. This is done voluntarily.
2nd phase- contractions of thee pharyngeal walls is what enables food to move through the pharynx. Elevation of the soft palate prevents food from entering into the nose. Elevation of the larynx and epiglottis prevents food from entering into the air passages. Communications with the cavity of the mouth is prevented by the base of the tongue.
3rd phase- Passing of the fod from the esophagus to the stomach.
The 2nd and 3rd phases are involuntary.

Fill in the blank The G0 phase can occur before the phase?
The G phase of the cell cycle is split into two sub-phases: the G1 and G2 phases. In between these two phases is the S phase (the synthesis phase). One can say the G phase (or the first of the two G sub-phases) occurs before the S phase.
What 4 phases are found in the M phase?
The four phases found in the M phase are prophase, metaphase, anaphase, and telophase. These phases involve the condensation of chromosomes, alignment of chromosomes at the metaphase plate, separation of sister chromatids to opposite poles, and formation of two new nuclei.
What consists of the G1 S and G2 phases of the cell cycle.?
During the G1 phase, the cell grows and carries out normal functions. The S phase is when DNA replication occurs, resulting in the duplication of the cell's genetic material. The G2 phase is a period of preparation for cell division, where the cell continues to grow and synthesize proteins needed for division.
What are the phases of the menstrual cycle?
The menstrual cycle has three phases:1) Menstruation - this is when bleeding occurs due to the shedding of the endometrium (the uterine lining).2) Follicular phase - this is when the follicles develop. The follicle contains a single ovum, or egg. At the end of this phase ovulation occurs, which is when the egg is released from the follicle.3) Luteal phase - during which the corpus luteum forms. This phase can end with either pregnancy or the degradation of the corpus luteum.

How many phases are usually involved in the a paper chromatography?
There are typically two phases involved in paper chromatography: the stationary phase (the paper) and the mobile phase (the solvent). The stationary phase is where the separation of components occurs, while the mobile phase moves the sample through the paper to facilitate this separation.
What are two names of the two phases of the heartbeat?
The two phases of the heartbeat are systole (contraction phase) and diastole (relaxation phase).
What are the 2 major phases of mining?
The two major phases of mining are exploration and production. Exploration involves identifying potential mineral deposits and assessing their viability, while production involves extracting and processing the minerals for commercial use.
